Guide to Commercial HVAC Repairs

The average homeowner isn’t usually very familiar with HVAC systems. It’s easy to think that a commercial HVAC system functions exactly like it does within residential households, but at a larger scale. You can get a proper understanding of different HVAC installation types by visiting this site:

Although both home and commercial HVAC systems are similar, their maintenance and repair needs differ. The preventive maintenance that’s performed on your residential HVAC unit isn’t sufficient for a commercial HVAC unit supplying the needs of an entire office or business building.

We’ve prepared a set of guidelines to help cover the possible problematic scenarios you may experience that require commercial hvac repair and the best practices to prevent significant and costly HVAC repairs.

HVAC and air conditioning: Key differences to consider

Experts and industry professionals use the terms HVAC and AC mutually; however, there is a difference. AC is simply shorthand for air conditioning, and refers to the way that the system “conditions” the air to adjust its temperature and provide heating or cooling as necessary.

On the other hand, HVAC, short for heating, ventilation, and air conditioning, and as it suggests, governs the entire ventilation and air duct system within a household or commercial space. This means that HVAC systems will almost always include air conditioning, but an AC is not necessarily an HVAC system on its own.

These separate air conditioners are ways to cool individual rooms or spaces, and they do not always include heat or ventilation. For example, window units and mini-split systems are AC units that are not HVAC units.

Meanwhile, you have an HVAC system if you have a central air conditioning system (a common way to cool and heat your home). They are connected through complicated ductwork to cool, heat, and ventilate the whole house. When properly managed and maintained, these systems can last more than 15 years, and below is how;

Maintaining your thermostat performance

Similar to the CPU of a computer system, the thermostat controls the entire functionality of the HVAC setup, and is where most customers engage with commercial HVAC repair. When it fails, a HVAC commercial repair firm is the best option to consider.

Fixing a thermostat is an easy task, but it’s also a simple task of keeping it in good working condition by making sure it is grounded to prevent electrical damage and using self-diagnostic tools on those models that have the technology built in.

The good news is most problems with commercial HVAC repair come from this unit and that fixing them can be relatively inexpensive compared to other issues.

When to change your HVAC filter

Most experts and technicians would recommend a filter change on a regular basis, usually allowing for a few months between replacements at most. It’s essential to have regular inspections performed for your HVAC filter and to have them swapped out as necessary for optimal performance.

Depending on several factors, such as the overall size of your home, the presence of pets or high allergen levels, and general air quality factors, your HVAC system might require more frequent filter replacements. Some might even require a monthly change depending on the overall circumstances where you’re living.

What happens when you don’t replace your air filter?

Built up dust and debris can lead to inefficiencies in your HVAC system, which means it’ll work less effectively and consume more power to do so. This is a serious issue that can reduce the lifespan of your HVAC system, increase the cost of your energy bills, and require more frequent maintenance to repair breakdowns or damaged parts.

Often times, an unclean filter is a major factor in inefficient HVAC performance. It can obstruct proper airflow and affect your temperature sensors, leading to incorrect temperatures being maintained and irregular operation times.

There are also other potential issues that can come about from a dirty air filter, such as increased moisture that promotes mold and bacteria growth, and an increased chance of your equipment overheating or building up ice within its components due to extreme temperatures.

Why your AC might be heating instead of cooling

An incorrect setting on your thermostat is usually the main culprit in high temperatures despite an operational AC. If your thermostat is on the heating option, or if you’ve manually set the temperature too high, it might explain why your indoor temperature is warmer than needed.

Whether your AC unit is even turned on might be why as well. If you haven’t turned on the AC, or if your AC is off and set to Fan, your unit might still be circulating heated air throughout the home.

Another alternative to the issue is that your air filter may need to be changed. A clogged air filter restricting proper airflow and preventing heat exchange is a probable cause for AC units not cooling properly.

In some HVAC units, the components may have become damaged or clogged with debris such as leaves, dirt, or branches. It may also not be receiving power properly and failing to properly disperse the heat into the outdoor atmosphere.

Finally, note that HVAC systems run on a refrigerant that is responsible for keeping your home cool and facilitating heat exchange. A leak or over-used refrigerant lead to inefficiencies and an HVAC system that isn’t cooling correctly.

The bottom line is that some of these difficulties require a professional to inspect your system to ensure it is operating properly. We do not recommend DIY (Do It Yourself) HVAC repairs since there are many problems that you may not be able to recognize, and you may inadvertently do additional damage in the future.

Electrical Issues

Some HVAC systems may run into issues caused by electrical damage, including anything from tripped breakers and damaged fuses to more severe complications. When this happens, an upgrade might be in order to update your HVAC system to deal with the needs of your electrical wiring.  Despite the additional cost,  you’ll be able to protect your commercial HVAC system from further issues or damage down the line.

Four signs your heating and air conditioning unit needs to be repaired

Not generating enough heat or AC blowing hot air – If the air from the heater isn’t as hot or the AC is blowing hot air, your facts might be damaged, or your burner may be obstructed by debris.

Unit keeps turn on and off – If your HVAC system is continually turning on and off, there might be electrical issues preventing proper power delivery, or your system might have debris or other clogged regions that require cleaning and replacement.

Airflow issues – If the air blowing out of your vents is weak and isn’t the right temperature, your ducts might have something in them obstructing proper airflow, or you could have a problem with your fan.

Hasn’t been maintained regularly – If you haven’t had HVAC maintenance done in years, consider hiring an HVAC commercial repair company to perform maintenance and ensure proper function


Getting an HVAC commercial repair company to repair your HVAC system will ensure the durability of your system.
